Specification of Letters Patent.

Application filed May 22,1907. Serial No. 375,171.

To all whom it may concern."

Be it known that THOMAS H. STAGG and JOHN B. ARMACK, citizens of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certainnew and useful Improvements in Tie-Cars for Impregnating-Tanks, of which the following is a specification.

Our invention relates to an improvement in bails for tie cars for impregnating tanks, and also improved means for locking the bail in operative position. The bail is preferably semicircular and hollow, and is constructed adjacentits ends so as to engage with a gravity look, so that any upward stress upon the bail would cause it to become more tightly locked.

The object of our improvement is to furnish a light and inexpensive bail which is at the same time strong enough to meet all contingencies, and further is quickly and securely locked automatically in engagement with the ends of the bolster.

In the accompanying drawings which are hereto attached and hereby made a part of this specification, Figure 1 is an end View of a tie car with the bail in place, in partial section; Fig. 2 is a side view of the automatic lock; Fig. 3 is a rear view of the lock in position; Fig. 4 is a section through the bail looking downwardly upon the upper end of the bolster; Fig. 5 is a transverse section of the bail. 7

Referring to the drawings, 1 is the wheels of the car appropriately mounted at 2, 3 is the side sill in place thereon, showing the same forming a covering for the wheels; 4 is the end sill having the portions curved upwardly and outwardly at 5, and terminating at any desired height. The end sill is usually spoken of as the bolster, and as seen in Fig. 1, it is formed of a channel having its upper face grooved from a point adjacent one end to a point adjacent the other end. Adjacent each end the groove is omitted, leaving a smooth face 6, as appears clearly in Fig. 3. The flanges 7 and 8 on said bolster, however, are retained, and a bolt 9 is inserted through openings in said flanges; through the face 6 is formed an opening 10. Pivot-ally suspended from the bolt 9 is a cam lock 11, having the extended portion 12 and the arm 13 extending downwardly therefrom; the forward portion of the cam face 12 is adapted to project into the opening 10. The inward movement of the arm 13 is determined by the lug 14 positioned within the channel, but it will be noted that the arm 13 may freely swing outwardly. The bail 15 forms a semicircle and is semicircular also in crosssection, thereby rendering the same light and at the same time strong enough for all'contingencies. The upper face is convex, whereby a smooth rounded upper exterior is provided, and on account of the lightness of the bail it is easily positioned or removed from the bolster. Its construction also requires much less material than the bail now in common use, and therefore not only has the advantage of strength but also is very light in weight and inexpensive. Adjacent its ends, the bail is flattened as appears at 16, so that it may form smooth engagement with the channel 6; through the bail adjacent its ends is provided the opening 17. l The bail is positioned by lowering the same until the openings through the ends register with the openings through the upper portions of the bolster, the arm 13 of the cam lock having been previously lifted approximately to a position at a right angle with the end of the bolster. When the openings 10 and 17 are thus brought into register, the arm 13 is dropped, whereupon the cam face 12 is projected into the openings, the upper face of the opening through the bail resting upon the upper portion of the cam lock. The inward movement of the arm 13 is limited by the lug 14, so that any upward pull upon the bail would more securely lock the same to the bolster.

It is not necessary that the arm of the cam lock be lifted by hand, as the same will be thrown outwardly by lowering the end of the bail thereon, whereupon a slight pressure will cause the lock to rotate on the pivot 9, which will permit the bail to be lowered until the openings register, whereupon the cam portion 12 will swing upwardly and enter the openings, and positively lock the bail and bolster together. The same result is accomplished at both ends of the bail at the same time. During the process of impregnating the ties, the latter have a tendency to float off the car, but any movement upwards against the bail merely tightens the lock. To unlock the bail, it is necessary only to swing the arm outwardly until the cam portion has been withdrawn from the openings, whereupon the bail may be lifted upwardly and removed. The construction described provides a bail which is light, strong, requires only a small quantity of material and is therefore cheaply constructed, and furthermore is automaticallylocked into position by a cam lock which is simple in its construction and easily made.

We claim:

, 1. In a car a bolster having its ends curved upwardly and outwardly, a hail having its ends adapted to be brought into engagement with the ends of said bolster, and means for automatically locking said bolster and bail together.

2. In a car a bolster having its ends curved upwardly and outwardly, a ball adapted to have its ends brought into engagement with the ends of said bolster, said bolster and bail having openings adapted to register, and a gravity lock adapted to project into said openings to secure said parts in place.

3. In a car bolster having openings adjacent its ends, a

bail substantially n shaped in cross section, having openings adjacent its ends, adapted to register with the openings in said bolster, a lock pivotally mounted on said bolster and adapted to project into said registering open ings, whereby said parts are locked together.

curved bail having openings ndjucent its ends adapted to register with the openings in said bolster, a pivoted lock adapted to be swung out of locking position by said bail when the latter is being positioned, whereupon said lock through gravity is projected into said registering openings to lock said parts together.

In a car a bolster having openings adjacent its ends, a bail having openings adjacent its ends adapted to register with the openings in said bolster, a pivoted lock adapted to be swung outwardly when said bail is being positioned. and adapted to swing inwardly to project into I 1 i l l l l l l said openings to lock said parts together, and means for limiting the inward swing of said lock.

6. In a car a bolster having openings adjacent its ends, a hall having openings adjactnt its ends adapted to register with the openings in said bolster, a pivoted lock adapted to project into said registering openings, whereby any upward stress upon said bail will cause said lock to be more securely positioned in said openings.

In testimony whereof we aflix our signatures in the presence of two witnesses.
